I took it for a test in my car to work this morning and everything worked out fine. I still need to wire the computer properly so I will get back with a report on how well it performes when cranking, startup/shutdown etc!

That's a 54W supply with no negative rails and an exceptionally week 12V rail. It also doesn't make it too clear what input voltages it works with. Still, more competition in this segment is a good thing.

I'm eager to learn more about the radio too. It says they plan to do audio over USB. That sounds nice!
